Aniston has an idea of “destination wedding, kind of like eloping with a few friends,” a source tells a leading media tabloid. “There will be the feeling of a vacation, since that's their favourite thing to do.”

But Theroux is of the view of staying close to his East Coast home.

“Justin wants a New York City winter wedding," a source told media tabloid.

The tone and theme of their future nuptials is also a source of contention. Although 43-year-old Jennifer will want to “celebrate in high style,” the friend explained, “Justin isn't as flashy as the men she's been with in the past, so it won't go too over-the-top.”

“Jen is over the moon about her second chance at a happy marriage,” a source of the actress tells the magazine. “Justin is giving her a solid vow to love.”

It will be the first marriage for 41-year-old Theroux, who split from longtime love Heidi Bivens in early 2011 after 14 years together, While Aniston divorced Brad Pitt in 2005.
